Abstract: Incremental but fundamental changes are currently being made to fuel composition and combustion strategies in order to diversify feed-stocks, decrease pollution, and increase efficiency. This rapid increase in parameter space makes it difficult at best to propose strategic changes to engine and fuel design using conventional build-and-test methodology. In order to make changes in the most time- and cost-effective manner, it is imperative that new computational tools and surrogate fuels are developed. Currently, sets of fuels are being characterized by the CRC fuels for advanced engines group as test fuels so researchers in different laboratories have access to fuels with consistent properties. In this work, seven gasolines (FACE A, C, F, G, I, J and HFC III) are characterized by the advanced distillation curve (ADC) method to determine the composition and enthalpy in various distillate volume fractions. Tracking the composition and enthalpy of distillate fractions provides valuable information for determining structure property relationship and, moreover, it provides the basis for the development of nist-equations of state that can describe the thermodynamic properties of these complex mixtures and lead to development of surrogate fuels composed of major hydrocarbon classes found in target fuels.
